Spray hitters ala Rod Carew and George Brett are hard to come by. They don’t make’em like that to often now days. To bad they put the DH in the National League IMO. Some teams had good hitting pitchers and the approach to the game just ain’t what it used to be.
Pitchers make too much money so they are reluctant to hit. Even if they are naturally good hitters (there are a couple). That's the downside of them making all that dough. Pitchers are specialists.
Pitchers didn't get paid too much money back in the old days so they were willing to hit the ball. But if they have a 100 million dollar arm? Forget it.
